Featured Reviews

Charles Slaustas - PeerSpot reviewer

Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.
Bill H. - PeerSpot reviewer

Affordable, easy to use, and integrates well with Active Directory
The product and service are already great as it is but if I could add one feature, I guess it would be nice to have another factor of authentication (two additional factors) like your phone and a token for example, for when people forget their phone at home. It’s not that I mind not having two factors, but I do get that question from time to time from some of our users who think it would be really useful. From what I’ve heard, they’re working on it and it should be coming in the next version so that’s great news.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."
"Cisco Duo seems very scalable—in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"The anti-phishing feature is the most valuable."
"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."
"Cisco Duo is rock solid in terms of stability and reliability."
"Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application."
"Cisco Duo helps minimize the risk of attack vectors and prevents unauthorized access to our data since it's tied with multi-factor authentication, which helps block threats."
"The solution is easy to use."
"We mainly implemented UserLock for multi-factor authentication, but the user login insights are also nice."
"The most valuable features are two-factor authentication and real-time logon monitoring."
 

Cons

"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"There was an issue related to integration with third parties."
"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."
"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it."
"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."
"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."
"Regarding the stability and reliability of the Cisco Duo solution, we have experienced some outages over the last few years that are significant because people can't log in."
"The product and service are already great as it is but if I could add one feature, I guess it would be nice to have another factor of authentication (two additional factors) like your phone and a token for example, for when people forget their phone at home."
"I would like to see UserLock add the ability to automatically create a group policy in Active Directory. That might streamline the setup process."
 

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"You will be hard-pressed to find better pricing."
